5-axis Iso-scallop Tool Paths along Parallel Planes

Abstract

To cite this version:Christophe Tournier, Claire Lartigue. 5-axis iso-scallop tool paths along parallel planes. ABSTRACTThis paper presents a new method of computing constant scallop height tool paths in 5-axis milling. Indeed, usual iso-scallop tool path computation methods in 3-axis or 5-axis milling generate tool path self-intersections, which prevent from reaching the required quality and productivity. The proposed approach consists in following parallel planes in 5-axis milling to avoid self-intersection of the tool path. The constant scallop height is guaranteed by modifying the machined strip width by means of the orientation angles of tool axis (yaw and tilt angles). Resulting scallop height and surface roughness are simulated using the N-Buffer method.

An Algorithm of Non-Iso Parameters Cutting Path Planning Using Toroid Cutter

“…So toroid cutter machining of free-form surface became hot issues of the current study. Article [1] presents a new method of computing constant scallop height tool paths in 5-axis milling. Article [2] reports tool path generation by the iso-scallop height method for the three-axis ball-end milling of sculptured surfaces.…”
